Many of the phone makers at the show placed a huge emphasis on camera technology, especially in regards to High Dynamic Range (HDR) and low-light photography. With more and more people using their smartphones as their primary cameras, this is great news. HTC's One X, One S, and One V cameras will come with the HTC ImageChip and ImageSense software, which has an almost no-lag shutter speed, an f2.0 aperture, and a handful of different shooting modes--including High Dynamic Range (HDR) and Panorama.
The Nokia 808 PureView (shown) has a 41-megapixel sensor. Like most high-end Nokia phones, the 808 uses Carl Ziess optics, plus a new pixel-oversampling technology. You don’t necessarily need to use all 41 pixels in your photos; you can switch between standard resolutions like 2/3, 5, and 8-megapixels. But having those extra megapixels at hand means you can capture an image, zoom in, reframe, and crop without any noise or pixelation.
